COMBING MACHINE.

Application filed February 25, 1925.

To all whom may concern.

Be it known that I, J OHN W'ILLIAM Ni-is MITH, a subject of the King ofGreat Britain, and a resident of Heaton Mersey, Manchester, in thecounty of Lancaster, England, have invented new and useful Improvementsin Combing Machines, of Which the following is a specification.

In British Letters Patent No. 132,987, corresponding to U. S. Patent No.i,369,532 dated Feb. 22, 1921, granted to me, there is shown a method ofadjusting, along an are having a common centre with the combingcylinder, the pivot on which the nipper of a combing machine swings, andof utillzing this adjustment to regulate the approach of the nipper tothe detaching roller. It is shown how each nipper can be individuallyadjusted and then how all may be simultaneously regulated to approachthe detaching roller within any required distance, and the pivot havingbeen brought to the de sired position it was secured there by theclamping screw 13, Figure I, aided by the screw 5 for eachpivot-carrying lever.

It has been found in practice that for certain classes of work it isadvantageous to give to the pivot N a slight oscillating movement alongthe arc r-o during each stroke of the machine.

The object of the present invention is to provide means to effect thisand in order that the invention may be understood I append a sheet ofdrawings.

In carrying the invention into effect I substitute for the screw 5 abovementioned a screw similarly designated in the append.- cd drawing. Thisscrews up against the framing of the machine (not shown to avoidcomplication) but does not clamp the lever 3 thereto, but being providedwith a. broad head it holds the lever 3 near the surface of the framingand supports it, whilst leaving the slot 4 free to ride over the shankof the screw 5 which passes through the slot 4-.

Similarly I substitute for the clamping screw 13 a stud similarlydesignated in the appended drawing, which can be fixed at any point inthe slot 12 of the graduated quadrant keyed on the shaft 10 on whichSerial No. 11,535.

is also keyed the lever 9, which is connected to the lever 3 by the rod7 with adjusting nuts 8. On the stud 13 is hinged the eccentric strap Eoperated by an eccentric X keyed on the cylinder shaft C. It will beobvious that all the nipper pivots N along the machine can be setindividually in line with the detaching rollers D by means of the rod 7and the nuts 8 and that as the eccentric X revolves a slight rockingmovement will be imparted to each pivot N, the time of which can beregulated by any suitable adjusting means on the eccentric. By suitablydisplacing the position of the stud 13 in the slot 12 this rockingmovement can be caused to occur at any point along the arc R-R withinthe limits of the slot 4.

By using a cam in place of the eccentric an irregular movement can beimparted to the stud N in place of the regular one obtained from a crankor eccentric.

I claim 1. In a combing machine wherein the pivot of the nipper in saidmachine is moved along an are having a common centre with the combingcylinder for the purpose of adjusting the relation of the nipper to thedetaching roller of the combing machine, means for giving the said pivota slight oscillatory motion at each stroke of the apparatus, such meanscomprising, a lever carrying the pivot, an arcuate sliding bearing forthe said lever formed on an arc struck from the centre of the combingcylinder, and means for imparting from the cylinder shaft an oscillatorymotion to the lever at each revolution of the said shaft.

2. In apparatus as claimed in claim 1, means for imparting from thecylinder shaft an oscillatory motion of the pivot carry ing lever, suchmeans comprising an eccentric strap on the said shaft, the end of saidstrap being connected to a stud adjustably scour-able in a slottedquadrant borne by a shaft and a lever arm on such shaft to operate thepivot carrying lever.

In testimony whereof I have hereunto set my hand.

JOHN WILLIAM NASMITH.
